通过采用众多纺丝技术,对纤维的结构控制已从微米级发展到纳米级。对纳米级纤维结构控制的重要性可以用两个方法来说明。一是给出模型或概念用以改善如结晶尺寸和分子取向这样的物理性质。这种方法是将宏观性能与纳米级结构联系起来,对聚合物设计和纤维结构来说是非常重要的。另一个方法是关于纳米纤维本身。此次研究将展现纳米纤维拥有哪些新的或者说优越的性能。
Through the use of numerous spinning technologies, structural control of the fibers has evolved from micron to nanometer. The importance of controlling the structure of nanofibers can be explained in two ways. One is to give a model or concept to improve such physical properties as crystal size and molecular orientation. This approach relates macro performance to nanostructures and is important for polymer design and fiber structure. Another method is about the nanofibers themselves. This study will show what new or superior properties nano-fibers possess.
